The 370 Ma Karamea Suite plutonic ‘flare-up’ event in New Zealand: the world’s hottest S-type? Rose Turnbull Associate Lecturer Geological Sciences University of Canterbury -------------------------------------------------------------------------------- High-precision U-Pb ID-TIMS geochronology from the voluminous (≥37,500km3) Devonian Karamea Suite in western New Zealand suggest that the entire suite of ‘S-type’ granites were emplaced within a ~2.1 Ma burst of...

EPA 525.2 for the Analysis of Organic Contaminants in Water (Webinar)

submitted by: Chrom Solutions
This webinar reviews EPA Method 525.2 (SPE-GC-MS method) for the analysis of organic contaminants in drinking water. In order to achieve the low detection limits, water samples are extracted and concentrated prior to injection into the GC-MS. Automated systems remove the laborious, less accurate steps of vacuum systems and at the same time, save solvent and cost less overall. Speakers: Beau Sullivan (Santa Clara Valley Water District), Richard Jack (Thermo Fisher Scientific). Visit...

Pesticides and Herbicides: A Growing Concern (Webinar)

submitted by: Chrom Solutions
This webinar describes using suppressed ion chromatography--mass spectrometry (IC-MS/MS) for glyphosate (a widely used broad-spectrum herbicide) analysis with the result that required reporting limits can be achieved without time-consuming derivatization. In addition, a validated extraction method for weathered toxaphene (banned since 1990) and its degradation products in fish tissues using Accelerated Solvent Extraction is also discussed. Speakers: Diana Burdette (US EPA R4 SESD), Stuart...

Provenance of mid-Tertiary sandstones and conglomerates from the California Continental Borderland; implications for paleogeographic reconstructions Shane Peterson M.S. Candidate Department of Geological Sciences San Diego State University Advisors Dr. David Kimbrough ABSTRACT The reconstruction of the Southern California Continental Borderland is constrained by interpretation of widespread Tertiary fluvial-deltaic systems, which contain a primary record of tectonics and...

Fault zone architecture of the San Jacinto fault zone in Blackburn Canyon: evidence for fluid flow in the shallow brittle crust during rupture events Daniel Pelikan M.S. Candidate Department of Geological Sciences San Diego State University Advisors Dr. Gary Girty ABSTRACT The San Jacinto fault zone is exposed in Blackburn Canyon in a stream cut channel 15 km SE of Hemet, California. The fault is bounded on the NE by the Thomas Mountain Tonalite, and the Bautista Metamorphic...

Determination of Volume Loss and Element Mobility Patterns Associated with the Development of the Copper Basin Fault, Picacho State Recreation Area, Se California, USA Thomas Colby M.S. Candidate Department of Geological Sciences San Diego State University Advisors Dr. Gary Girty ABSTRACT Since it was originally mapped in the 1970’s, the structure referred to herein as the Copper Basin fault has been incorrectly interpreted as an “arcuate”, north-dipping normal fault....
